Hi Lukas,

It's great to coro land.

I'm now getting these errors trying to build coroutine.cpp on MacOS X 10.5.8:

./hotspot/src/share/vm/runtime/coroutine.cpp: In static member function 'static Coroutine* 
Coroutine::create_coroutine(JavaThread*, CoroutineStack*, oopDesc*)':
./hotspot/src/share/vm/runtime/coroutine.cpp:282: error: 'coroutine_start' was not declared in this scope
./hotspot/src/share/vm/runtime/coroutine.cpp: In member function 'bool Coroutine::is_disposable()':
./hotspot/src/share/vm/runtime/coroutine.cpp:347: error: 'coroutine_start' was not declared in this scope
